✓ Reviews all syllabus points ✓ Great topic review or revision resource ✓ Can be cut into revision cards ✓ Key to highlight level of understanding ✓ Encourages independent study, knowledge retrieval practice and metacognition Topics included: B1 Characteristics of living organisms B2 Cells B3 Biological molecules B4 Enzymes B5 Plant nutrition B6 Animal nutrition B7 Transport B8 Gas exchange and respiration B9 Coordination and response B10 Reproduction B11 Inheritance B12 Organisms and their environment B13 Human influences on ecosystems This review worksheet is designed for students enrolled in the Cambridge IGCSE Coordinated Science 0654 (2023-24) course, and covers the all topics. The worksheet is divided into different boxes to help students break down the information and organise what they need to know. It is double-sided and should be printed on A3 paper for students to complete. If printed single-sided, students can also cut the little boxes into flashcards for further study. The tasks are split into different boxes to help students break down the information and organise what they need to know. This resource has been designed so that students can highlight the worksheet, rating each box either red, amber or green. There are no answers supplied with this resource. When I complete this I ask students to highlight their boxes as follows: Green - The student can complete this in exam conditions (This means the student understands and remembers this information) Amber - The student can complete this after checking their notes, resources or asking a classmate (The student understands this but doesn’t remember it) Red - The student can’t complete this without asking for serious help (The student doesn’t understand or remember this) You can then go over the answers for the remaining red sections with the class at the end of the lesson. This system helps students to think about the importance of knowledge retrieval and metacognition when revising. It also allows the class to settle by asking them to working in exam conditions by completing the green sections first at the start of the lesson. Finally it allows you to have immediate visual feedback about student understanding of your teaching. This lesson would also be adaptable for all GCSE students (whether AQA, Edexcel, OCR) and great for KS3 Science or as a GCSE revision resource.
